Does anyone have a tricky input that would show me why I'm getting WA? I can't find any errors in my program, but apparently it's wrong. Thanks.

Pay attention to the description of the problem

Don't use any unnecessary spaces at the end of the line.

hope this can help u

First time got so frustrated with a problem. Got WA at lesat 10 times. Could anyone help...at least provide me 1 input that fails my program? Thanks in advance.

Any ideas? Any at all?

Although the first and third cases are identical, your output for these cases is not!
Please don't ask me to find the bug in your code. It has something to do with the middle case: remove it from the test file, and your output is correct again...
Funny

Happy hunting.

Heh... that's weird alright. Guess that's why they call you Guru.

For my reference, could you let me know what AC output looks like for that input? I'm still a little unclear on a few things. For instance, it's my understanding that for the black ones, you leave them blank if there's a direct path to the edge consisting only of other black ones, and you fill them in otherwise. Is that accurate?

Time to hunt for that bug

Thanks again.

Posted: **Fri Aug 27, 2004 11:35 pm**

Okay you know what's even weirder? I just got AC (well, PE) after making the following change. At the beginning of my init() method I call a method called crazy_kill_all(void), which goes as follows:

[cpp]
/* Should do nothing; might make my program work */
void crazy_kill_all(void)
{
last_row = 0;
for (int i = 0; i < MAX; i++)
{
for (int j = 0; j < MAX; j++)
{
board[j] = 0;
visited[j] = false;
}
end_of_line = MAX;
}
}
[/cpp]

Pretty crazy eh? I think it might be some subtle bug with the visited[][] array; I might want to look into that further.

EDIT: Okay I found the bug for sure. Very idiotic of me, I must say! I didn't really need the crazy_kill_all after all, just needed to change a few < signs into <= signs. Glad to be done with this one... though, I'm still a bit muddled by the PE.

Posted: **Sat Aug 28, 2004 1:45 am**

Good for you that you got AC, don't worry too much about that PE. Can't remember the verdict I got, but most of the time I just ignore them. Guess you don't need that output anymore.
I like the idea of a crazy_kill_all(), although it's a sign of weakness

, I should remember that trick comes time...
My Linux clock is telling me it's 1:45 in the AM, so I'm turning in now.

i dont understand what is wrong with my code?????
just getting WA.
but it seems all ok.
Any tricky input here or what?
can anyone help me????????
THANKS.

but i'm not sure if this is correct.

My code is:

Code: Select all

cut after AC

Thanks

Posted: **Tue Jan 17, 2006 9:11 pm**

Code: Select all

    for (int i=1; i<=n; i++) 
    { 
      if (M[i][1] == 0) elimina(i, 1); 
      if (M[i][n] == 0) elimina(i, m); 
    }

In the above section

Code: Select all

      if (M[i][n] == 0) elimina(i, m);

should be

Code: Select all

      if (M[i][m] == 0) elimina(i, m);
